It's a known problem caused by a lot of different situations. It's sad
that a lot of important applications suffer of this problem. I'm working
with Axis, and just trying to reload the bundled webapp never release
the old WebappClassloader.
I think this is serious: hot deployment becomes totally useless and you
have to restart tomcat each time you deploy a new version :-(
